Can the osteosynthesis with locking plates be a better treatment for unstable fractures of the proximal humerus?

PURPOSE: The purpose of this study is to review our experience with proximal humeral locking plates, including complications, functional outcomes, strength recovery and predictors of successful treatment.

METHODS: Seventy unstable proximal humeral fractures were treated with open reduction internal fixation (ORIF) with the use of locking proximal humerus plate. At an average follow-up of 31 months, the clinical and subjective outcomes were evaluated, and complication was analysed.

RESULTS: The average Constant score was 72. The mean disabilities of the arm, shoulder and hand score was 23. The average range of motion was as follows: mean range of anterior elevation and abduction 120°-150°; external rotation in abduction 64° and in adduction 44°; and internal rotation T12.

CONCLUSION: On the basis of the overall functional and clinical outcome obtained, it is possible to suggest that the ORIF of the proximal humerus fractures using locking plate represents a helpful option that can lead to a good clinical and functional outcome even in the most complex fractures.
